We are all pupils but are we all willing to learn.
There is no chance meeting. Everyone who crosses our path has either something to teach us, something to learn from us, or both. Allow yourself to be open to everyone who enters your life. Whether they be here for a minute or a lifetime. Teach without teaching and learn without judgment.
Take what you have learned and give to others. Allow them to pass it on. For once you own it, you must give it away to keep it.
